EDW M. BEEBE, OF CUSHING, OKL "x SLUSH-LPUMP MANIFOLD.

Application filed April 14, 1928. Serial No. 270,080.

My invention relates to improvement in slush pump manifolds,particularly applicable for use in drilling oil and gas wells with whatis known as rotary drills.

5 The objects of my invention are to produce a device of the classdescribed which will be new, simple, novel, inexpensive, practical,

efiicient and of utility; which will automatically permit the shiftingof one pump to another in. the job in drilling with a rotarydrillingoutfit; which will prevent the necessity of the use of two .ormore expensive valves in connection with the drilling of such drillingoutfit; which will be stron durable and which will not easily get cgnt 0order; which tached and changed; which will eliminate the use of gatesnow required in such drilling; which will include a double valve havingboth ends the same edge of which is adapted to fit into the valve seatanother valve is introduced into the end adjacent the respective seattherefor; which eliminates a large number of parts required in formerslush pump manifolds; which eliminates the valve seat shown in aseparate piece at Figure 3 of the drawing in my former application forpatent for improvement in slush manifolds, filed December 14, 1927 underSerial Number 239,- 851; which eliminates the several separate parts ofthe double valve shown in Fig. 4 of said application just describedmaking in stead of them the double valve of one piece of metal each endof which is adapted to receive there surrounding a packing substance'for contacting the respective valve seats; which rovide standard ipethreading for the en s of the flanges or connection for other parts ofthe mechanism.

My invention consists of the novel features, construction andcombination of parts hereinafter more, fully described, illustrated inthe accompanying onessheet drawing, and pointed out in the appendedclaims; it being understood, however, that various changes [may be madein the form, proportion, size, shape, weight and minor details ofconstrucvtion, within the scope of my invention with-v out departingfrom the spirit and principle vantages thereof. 1

used, one of the essentials is a continuous and interrupted flow ofwater under pressure. TlllS water is forced through the pipe and In thedrilling of a well by a rotary drillmg outfit where two alternatingpumps are hose down the well throu' 'h a rotating-shaft a to therotating drill an out at the drill point into the casing whence it andthe loose material produced by the drillin is carried to the surface andemptied into 51c basin or pond. The sediment settles, the water clearsand is again ready for use in another cycle .of operation. If aninterruption in this process occurs the well or hole is exposed to muchdanger from caving in, closing up, and the like. All of these. and otherdisadvantages are obviated by my invention. .011 December 14, 1927,under Serial Number 239,- 851, I filed an application for patent underan improvement in slush pump manifolds. I desire this application to beconsidered as an improvement over and in connection with saidapplication. I claim an improvement over said former application in thatthe valve seats contain a less number of parts and will cost lessinmanufacture and installation and take less time in installing andremoving and the machined seat being in one piece Wlll be stronger andless liable to get out of order.

I also claim the double valve in this applithat the hydraulic packing isbetter posi- 'tioned, more substantial, more lasting and much lessliable to become loose and removed and get out of order.

I desire to have the drawing and these specifications to be consideredas illustrative I provide a longitudinal cylindrical body and notrestrictive only. One embodiment of my invention may be described asfollows 1 having a central upstanding flange 2 being L-shaped, having acentral bore 3 and having an L-shaped flanged member 4 thereabove forforming with said first flange 2 a union. Both of said members havingconjugate perforations 5 and 6 and being adapted to be securely heldtogether by bolts and nuts 7 and 8; said upper flange member 4 having acentral bore 9 with its upper portion having standard threads 10 forseating a stand-pipe 11 thereabove. On each end of body member 1 isprovided an L-shaped union 12, 13, being adapted to fit L-shaped flangedvalve seat members 14 and 15, said flanged member 12 and said valve seatmember 14 having conjugate perforations 16 and 17 therein for securelyholding together by bolts and nuts 18 and 19 and said flanged member 13and said valve seat member 15 having conjugate perforations 20 and 21'therein for securely holding them together by bolts and nuts 22 and 23.I prefer to have between said flanged portions 12 and 14, and saidportions 13 and 15 cylindrical shoulders 24 and 25 for more securelyholding saidmembers together.

I also prefer to have similar shoulders 24" and 25? between flangedmembers 2 and 4.

Said flanged valve seats 14 and 15 are preferably machined on theirinside surfaces and taper from points 26 adjacent said shoulders 24 and25 diminishing outwardlyrespectively therefrom to points 27, from saidpoints 27 outwardly to their respective ends 28 and 29 they arestandardly threaded 30 and 31. To these threaded end portions. areconnected pipes 32 and 33 connecting with slush pumps .34 and 35.

I also provide a double plug valve 36 sub- I I stantially barrel-shaped,being formed of one 40 piece of metal, preferably of steel The endportions 37 and 38 from points 39 and 40 from approximately the distanceof one third of thelength of said member from each end to points 42 and43 are tapered 44 and 45 diminishing from said points 39 and 40respectively to points 42 and 43. Intermediate said points 39 and 42 and40 and 43 I provide channels 46 and 47 encircling said barrelshapedmember the inner portions of said channels 46 and 47 being hollowed outinternallyon each side'from their respective peripheries as indicated bydotted-1n portions 48, 49 and 50, 51 for receiving and securely holdinghydraulic packings 52 and 53. I also provide frustum-shaped hydraulicpackings 52 and 53 for insertion within said channels 46 and 47 thewider dimension 54 thereof being adapted tobe inserted against the innersurfaces of said channels, and are intended to entirely fill saidchannels including their wider dimensions as shown by said dotted-inportions 48, 49 and 50, 51. Said hydraulic packing members 52 and 53 areintended to extend slightly beyond the tapered surfaces 44 and 45 butnot as far as points 39 and 40 thrown into operation.

on said surfaces. Any suitable hydraulic packing may be used. But Iprefer to use a good grade of packing for such purpose.

In operation when my device is attached to the pipe in working position,and to the stand pipe, the pump is started. This has approximately apressure of 500 pounds, or more. The water entering the body 1 of thedevice will immediately drive the valve 36 to the opposite end of thebody 1 from that in which the water enters and the valve 36 willimmediately close such opposite end; the hydraulic packing 52 and 53around such end will be forced against the machined inside surface ofthe valve seat thereby closing the port adjacent thereto against egressof water, and the like, through opening 3 in L-shaped flange 2 intostand-pipe 11, and thence into the hose, well, rotating shaft, etc, andout again. If the pump being used becomes disabled, or otherinterruption occurs, the other pump is then I The plug valve will thenbe driven to the opposite end ofgthe device where it will be lodged inthe tapered portion of the opposite valve seat. The flow of the wateroutwardly therethrough will be stopped and the liquid will then beforced through the same opening 3 thence into the stand pi pe, hose,well, rotating shaft, etc. and

out again.

can be supplied and installed easily and new hydraulic packing can beeasily and quickly installed on the double plug valve, bothof whichprocesses will be cheaply and quickly done without interferring'with theoperation of the drilling for any considerable length of time.
